This site - Writing Fix - is a site for teachers with lesson plans for classrooms. I looked at it and it can be slightly tweeked to apply to any writer. Just visit and look around. The address below takes you to a prompt generator. Below are three of the random prompts I saw.
"Too white? Too black? Too gray? Write about a place you once visited that was too much of one of those colors."
"Who do you suppose starts a 'legend'? Think back to something or someone from your youth that might have been worthy of 'legendary' status...at least from your child-like point of view. Write about it, using a 'legendary' voice."
"What might come from the mouths of babes? Write a humorous piece of fiction where a baby's first word is a little surprising."
